Expeditious Turn Around Time

  • 24-hours for most ophthalmic specimens (unless special studies are necessary for diagnosis)
  • Same-day interpretation on slide consultations
  • Five working days for enucleation and exenteration specimen

Personalized Communication

  • A confirmation is faxed upon receipt of the specimen identifying the pathologist interpreting the case and providing contact numbers.
  • The pathologist contacts the submitting physician when the biopsy findings require discussion. A faxed final report will follow.
  • The pathology outreach coordinator makes regular contact with your office to ensure quality of service.

Specimen Preparation and Transportation

  • Complete the requisition form and fax the form and the patient's demographic information to 317-491-6419 before sending the biopsy.
  • Place the specimen in the proper fixative (indicated below) and transport in a leak-proof hard plastic container placed in a zip-lock bag along with the submission form and all accompanying information, including the most recent clinical information.
  • Place all in a box or mailing tube filled with packing materials (paper towels, etc.)

  • Corneal Buttons: Formalin is not a universal fixative for corneal tissue. Please call 800.433.0740 before surgery when the anticipatited diagnosis will require the following:
    • electron microscopy
    • immunofluorescence or
    • the detection of crystalline substances, as fixation depends of the type of test required
